NARCISSISTIC PERSONALITY

I found this information online. It describes someone I know with frightening accuracy. Points 1,3,4,5 & 6 really hit the nail on the head. Approx 70% of people fitting this description are men and I wonder, do we all know someone like this?

Narcissistic Personality - Diagnostic Criteria:

A pervasive pattern of grandiosity (in fantasy or behavior), need for admiration, and lack of empathy, beginning by early adulthood and present in a variety of contexts, as indicated by five (or more) of the following:

1. has a grandiose sense of self-importance (e.g., exaggerates achievements and talents, expects to be recognized as superior without commensurate achievements)
2. is preoccupied with fantasies of unlimited success, power, brilliance, beauty, or ideal love
3. requires excessive admiration
4. has a sense of entitlement, ie, unreasonable expectations of especially favorable treatment or automatic compliance with his or her expectations
5. is interpersonally exploitative, ie, takes advantage of others to achieve his or her own ends
6. lacks empathy: is unwilling to recognize or identify with the feelings and needs of others
7. is often envious of others or believes that others are envious of him or her
8. shows arrogant, haughty behaviors or attitudes
9. believes that he or she is "special" and unique and can only be understood by, or should associate with, other special or high-status people (or institutions)

A profile of a pompous, superficial, lying bully with inch-thick skin and unshakable belief in himself. Someone who has always been and who always will be, unto himself, the number 1 priority. It's reassuring for me to know that this kind of (abnormal, surely?) psychology has been defined and discussed. That it is a known - categorised - quantity.
